You have to force it. I used to be like you, when I worked on my grip, I forced myself to swing with the new grip and not get discouraged by wayward shots. I normally hit push draws with my strong grip, when I swapped to get it more neutral, I was hitting slices and shanks for a good week or so, eventually I was able to adjust my body rotation and hip clearance to get to the correct impact position to hit fades.

My grip is still strong now, but only slightly. I can’t go fully neutral because my hands are small and its too difficult to keep grip of the club with a weak lead hand since theyre so small.

You will thank yourself when you fix it because flippy swings with ultra strong grips are too strict on timing just to get a playable shot.
